DESCRIPTION
The TPS5435x is a medium output current synchronous
buck PWM converter with an integrated high side
MOSFET and a gate driver for an optional low side
external MOSFET. Features include a high performance
voltage error amplifier that enables maximum
performance under transient conditions. The TPS5435x
has an under-voltage-lockout circuit to prevent start-up
until the input voltage reaches a preset value; an internal
slow-start circuit to limit in-rush currents; and a power good
output to indicate valid output conditions. The
synchronization feature is configurable as either an input
or an output for easy 180擄 out of phase synchronization.
The TPS5435x devices are available in a thermally
enhanced 16-pin TSSOP (PWP) PowerPAD錚?package.
TI provides evaluation modules and the SWIFT錚?Designer
software tool to aid in quickly achieving high-performance
power supply designs to meet aggressive equipment
development cycles.
